I was wondering if its beneficial to be in a higher gear in an automatic but have losses in the torque converter? I remember I had an astra before tho i did not experimented it properly i remember that if i activated snow mode which enables it to start at 2nd gear the FE reading in my UG drops significantly. Now i have a nissan maxima (no obd port so no UG to be installed) which loves to be in 3rd gear is this intentional by nissan engineers to save fuel? I tend to manualy downshift to 2nd to have a more direct power from the engine thinking that 3rd gear will have losses in the torque converter. Is my assumption correct?
